SPECIFICATION forming part of Letters Iatent No. 627,340, dated J' une' 20, 1899.

Application filed March 29, 1897.

which line may, if desired, be more or less' curved or irregular, and the eyelets may be set at a greater or less distance apart, my machine being particularly desirable for use in connection with boots and shoes.

The particular features in which my invention consists will be hereinafter fully set forth, and especially emphasized in the claims at the end of this specification.

Fig. 8 is a side elevation and plan view of the scale shown in Fig. l of the bottom or under set` and block carrying it; Fig. `9, a like-sealed side elevation ot' the top set and the block carrying it. Fig. 10 is a detail in side elevation, showing much enlarged the bottom and top sets and means for holding and adjusting them. Fig. 1l is an enlarged front view showing the top sets and their blocks; Fig. l2, a rear side View of the bottom sets and their adjusting means. -Fig. 13 is a plan view ofl Serial No. 629,772. (No model The reservoir A2 has, as shown, two hooked ears a suitably attached to it and so made as to embrace a part of the hopper A2, and said reservoir has also a slidin g door d and a springcatch d2. The hooked ears of` the reservoir engage a suitable pin a3, shown as on the stand, thus constituting a hinge-joint, the spring-catch holding the reservoir closed in working position, said catch at such time engaging a bar d4, forming part of the hopper.

To fill the reservoir, it will be turned over toward the right, viewing Fig. 2, and when filled the door will be closed and the reservoir Will be put back into the full-line position, Figs. l and 2,and the door will be raised and let the eyelets issue therefrom in a tapering pile, said eyelets resting on and slightly overflowing a shelf h, which is exposed at the bottom of the hopper. The eyelets which fall from the shelf drop upon and slide down the inclined top of the'bottom plate h' of the race-- way, some of them entering grooved bars b3, forming also a part of the raceway, as shown in Fig. 7. The upper ends of these bars are connected with a cross-bar h4 by suitable studscrews b5, so that said bars may be pivotally suspended from said cross-bar, said bar being connected by screws b2 with the bottom plate of the raceway. These bars near their lower ends are provided each with athreaded hole (see Fig. 6) to receive a stud-screw c', said screws entering diagonal slots @2in a bar shown as shaped like a yoke c3, having at its lower end an ear c4, which is slotted to enter an annular groove in an adjusting-screw c5, the threaded part of said screw entering a threaded lug c6, depending from the bottom plate the rotation of said adjusting-screw changing the position of the said bar and;

causing its diagonal grooves to act on the studscrews c and' spread apart or move toward each other the lower or delivering ends of the said grooved bars, according to the direction of movement o-f the said bar c3, the distance apart of the lower ends of those bars controlling the distance apart of the eyelets. The

bar c3 is slotted at c7 to receive ltwo screws CZ d, said screws entering threaded ears bs of the bottom plateh, said screws being surrounded by suitable springs cl3, which normally act to elevate the said bar c3 and with it the grooved bars, and so by turning these screws more or IOO less a space of greater or less width may be left between the under sides of the grooved bars and the top of the plate b for the reception of the flanged part of the eyelets, the space being adjusted to correspond with the thickness of the said flange. The under side ofthe plate b,near its termination,is provided with a cross-groove, said. groove receiving the upturned ends d6 of the racewayterminals C27, slotted at their delivery ends, as at 24(see Fi'g. 5,) for the reception of the plungers m of the lower sets. These terminals may be adjusted laterally on the plate b', and when put in adjusted position maybe clamped in such position by a clamp e', shown as an angle-bar, which is connected to the under side of the plate b' by a suitable clamping-screw e2. Each of these terminals has a stud e3 extended from it through a diagonal slot e4 in the bottom part of the bar c3, said slots corresponding in shape with those c2 in the top of the yoke, so that the ends of the grooved bars b3 and the ends of the terminals maybe spread or contracted in unison. The hopper contains a4 rotating brushf, fast on a suitable shaft f', driven by a suitable belt f2, thesaid brush sweeping upwardly at intervals over the incline b' the eyelets which rest thereon, thus keeping said eyelets sufficiently agitated so that they find their way right side up into the spaces of the grooved bars.

The lower ends of the grooved bars b3 are slotted at 24 for the entrance therein of the plungers m of the lower sets, and cooperating 'with these slots I have arranged a series of eyelet-stops f3, which enter lugs f4 on said bars, said stops being made adjustable by screws f5, so that they may act to arrest all the eyelets in the same horizontal lline or in any curved or irregular line, according to the shape which it is desired that the set ot' eyelets shall present in the material in which they may be set. v

As herein shown, my machine is made as a double machine-that is, it has two gangs of top and bottom sets, to he described, and they are arranged each in proper parts of the frame, and the framework has suitable bearings for the reception of two power-driven rotating shafts B in substantially the same line.

Both parts of the machine being substantially alike, I need herein describe specifically but one of them.

- The main shaft has a suitable cam B, which in the rotation of the shaft acts upon-the -endA of a lever B2, pivoted at B, the upper to move the entire raceway to the right, viewing Fig. l, sliding the same in the guideways 4g, forming part of a stand g', the said raceway moving from the full-line position, Fig. 2, into the dotted-line position, Fig. 2, the

upper end of the plate b entering the pile of eyelets on the shelf. This upward movement of the raceway also enables the eyelets to be discharged from the lower end of the raceway, but not, however, until after the plungers of the bottom sets, to be described, have entered the eyelets held at said lower ends. The reverse movement of the raceway is effected by the spring g2. The lower sets m', herein shown as'siX in number, are held -in suitable set-carrying blocks m2 m3 by suitable set-screws. The blocks m2 have at their lower ends dovetailed projections 'm4, which enter dovetailedgrooves in a plate m5, and the set-carryin g blocks m3 have a cross-groove m6, in which enters the anged edge of a screw 'm7, each of said screw-heads standing ina recess 'm8 in the plate m5, the threaded end of the screw entering a threaded hole in the plate mi". ByA rotating the screws m7 the said blocks m3 may be slid back and forth to put the sets carried by them out of line with relation to the sets carried by the blocks m2.

. These blocks m2 and m3 must also be adj usted at times to and from each other to place the eyelets at the proper distance apart to correspond with the position of the grooved eyeletguiding bars of the raceways. To eifect this latter adjustment, I have mounted in an ear n, at the rear of the block m5, a screw n', hav

ing a groove in its neck, a forked end of the ear n entering this groove, a threaded part'of the said screw entering a bar n2, having a dovetailed groove, (see Fig. 10,) in which enters loosely a series of dovetailed projections n3 at the large ends of a series of wedges n4, said Wedges occupying positions between the tapered sides of the blocks m2 m?, as shown in Fig. 12. The blocks m3 are all slotted, as shown in Fig. 8, to receive a clamp-screw a5, one end of which is screwed into one of the blocks m2, the head of the said screw acting against the outer side of the other of said blocks m2. By loosening this screw or turning it in one direction the blocks m2 m3 may thereafter be adjusted laterally. by the said wedges. When it is desired to adjust these blocks to separate the sets for the desired distance one from the other, the screw n may be turned in a direction to force the bar n2 and its wedges into the spaces between the blocks, and at such times the dovetailed part of the blocks m2 will slide in the dovetailed grooves and the blocks m3 will slide on the plate m5 and on the flanged edges of the screw-heads. The blocks m2 have each a shouldered screw as, and between the said shoulders and the under sides of the heads of said screws is a cross-bar 'm7, slotted where the screws stand in the slots, so that the said bar, while it keeps the blocks m3 seated on the plate m5, does not interfere with the lateral movement of the blocks m2. j

The bottom sets are hollow and rece-ive within their ends the usual spring-supported plunger m commonly used in eyeleting-machines. The upper or top setsh of corresponding number are held in blocks h h2 by IOO IIO

suitable screws h3, and these blocks 7L' h2 are mounted on and made adjustable on the plate h4 by wedges h5, controlled by a bar 7i and a screw k7, all as described particularly with relation to the adjustment of the hollow sets, the like-shaped devices being, however, designated by diiterent letters, as stated. These top sets, with the exception of the top-set blocks on which they are mounted and the provisions for adjusting said blocks, are all old and common. I/Vhen the cross-head and the lower sets are raised, the plungers in their ascent enter each the proper eyelet at the lower end of the raceway, and passing through said eyelet it meets the end of the upper set, at which time the raceway has imparted to it its upward movement, thus detaching the eyelets entered by the plunger-s from the lower ends of the raoeways. Thereafter the continued upward movement of the lower set while the plunger is arrested in its movement causes the lower set, it supporting the flanged end ot' the eyelet, to force the unlanged end of the eyelet over and upon the truncated end of the upper set, causing said set to spring outwardly and Iiange the small end of the eyelet, setting its small end closely upon the work.

By this machine I may set any desired n umber of eyelets-for instance, all the eyelets used in the half'of a top of a boot or shoe or all the eyelets in one-half of a corset or other article or thing where it is desired to use a large number of eyelets.

When the raceway is drawn back, the stop f3, holding` the eyelet at the end of the raceway, it being made as a spring, yields, letting the eyelet-shank pass the stop, and immediately thereafter the stop, due to its spring action, comes quicklyinto position between the eyelet then entered by the plunger and the one next back of it in the raceway, holding it in position to be entered at the proper time by the plunger at its next rise.

The main shafts have suitable clutch-pulleys, normally loose thereon, and under the control of a clutch operated by alever through the foot of the operator. This clutch mechanism may be of usual or desired construetion so long as the operator, by his foot upon the treadle, may at any desired moment start the shaft in rotation, letting` it run once and then automatically stopping it.

This machine, as has been stated, is made as a twin machine-that is, it has two distinct series of top and bottom sets arranged side by side, the sets of one series being so located as to eyelet the right-hand half of a shoe and the sets of the other half the left-hand side of a shoe, and with two such series of sets the eyelets may be set in a shoe without stopping to make any adjustments after the sets have been once properly positioned for a given style of shoe.

I have herein illustrated and partially described a brush-like agitator occupying a position in the hopper ,and extending transno claim is made herein to any of said devices,

tor the reason that I have chosen to make them the subject-matter of a claim in my application, Serial No. 685,016, filed on the 2d day of July, 1898.
